But I don't think it means the doctor will regenarate
Ты see in RTS's book it says that the doctor meats the doctor (I think that means future doctor) and then becomes his companion thats why it's called the Далее doctor, even though the doctor doesn't regenerate we see what the Далее doctor will look like
So to заворачивать, обертывание it up the Название "The Далее Doctor" doesn't mean that the doctor will regenerate it means that we see what the doctor will look like after hi regeneration which will be in a future episode
